Suppose no crossing - over takes place. explain why meiosis will still increase genetic variation

1 answer:

7 0

Answer:

Meiosis will still increase genetic variation due to 2 rounds of independent assortment through the two rounds of cell division that occurs during meiosis.

Explanation:

During the lining up of homologous chromosomes/ chromosomes along the metaphase plane, the homologous chromosomes/ chromosomes are attached to spindle fibres on opposite poles of the cell and positioned along the metaphase plane to enter either daughter cell independently of one another. Hence this will result in the variation combination of sister chromatids/ chromosomes in the resulting daughter cells.
